McCall to Price Road Trip: Idaho Mountains to Utah Desert

This 450-mile route follows US-95, I-84, and US-6 from McCall, Idaho to Price, Utah. The stretch crosses two states and three distinct geological provinces: the granitic Idaho Batholith, the Snake River Plain's volcanic basalt, and the Colorado Plateau's sedimentary layers.

One quirky detail: near Malad City, Idaho, you cross the Portneuf River, which flows into the Bear River that ends at the Great Salt Lake — a rare river that doesn't reach the ocean.
